<div dir="auto">They are at least 5 years old, which is when we bought the Optima and got our last set of housings and cell assemblies.<div dir="auto">There is also the possibility that a few are from San Antonio when I got the first optima in April 2017, but I had to leave most components that did not come with either of these optimas there when I left.

<p class="MsoNormal">It was nice speaking with you yesterday! I will pass this information along to our business unit and service team. I am sure they are going to inquire about the cell housing age. I assume you likely have a fairly decent amount of cell
housing and spare part inventory, but do you know how old these are? IE- when these particular cell housings were ordered/received?<u></u><u></u></p>

<p class="MsoNormal">We have a recurring issue with the glue used to keep the key guide inside cell housings in place. The glue seems to degrade/deteriorate over time, causing the key guides to fall out or pop up (see red circle), and when they stick out, they
prevent the user from inserting window holders or centerpieces, since the end of the guide pin is blocking it -see pictures below:<u></u><u></u></p>

<p class="MsoNormal">In the past I simply gave these housings to Richard Kanady (San Antonio) who would swap them out for me. I understand he took them back to their manufacturing and they would simply glue the keys back in. I got about 10 of them right now
in this state that are currently useless. It would be great if you could swap them out or fix them, we badly need them for multi-sample experiments. I already asked my service engineer (Amit Singh), but apparently there is nothing he can do about this without
the serial numbers on the housings, which are curiously all the same:<u></u><u></u></p>
